Crafting
This page lists all crafting recipes currently found within Project Zomboid, except for the Smithing recipes which are currently unobtainable in regular game and can only be learned by reading The Smithing Magazine which can only be spawned in debug mode, or by an admin in multiplayer servers and are likely to be available or totally disabled in upcoming versions.
Crafting items can be done by having the correct items in the player's inventory (or surrounding accessible inventories) and right-clicking one of the items, or in the case of custom food recipes, right-clicking the base/starter item. Any crafting recipe that an item can be used in will show up in the contextual menu. If that item can be used in multiple recipes, those recipes will also display, as long as the player has the correct items for them.
Crafting items can also be done through the crafting UI, which can be opened via the hotkey B by default, or pressing the HUD icon at the top-left of the screen 
. Recipes in the crafting UI are separated into categories, which are navigated via the tabs. Tabs will remain hidden until recipes from that category are learned.
Construction can be done by right-clicking an empty space to bring the context menu and then selecting either Metalwork or Carpentry, as long as at least one recipe is learned. Construction recipes do not appear in the crafting UI.
Disassembly of tiles can be done by right-clicking an item in question and choosing Disassemble and then selecting item to disassemble or using the last icon (Disassemble) from the Moveable Panel. Right tools are required to disassembly items, and disassembling items gives either carpentry or metalworking experience.
Crafting recipes can be learned by simply choosing the appropriate occupation or trait during character creation, reading recipe magazines, or, in case of constructions, reaching the required skill level.
The player's skill level doesn't directly affect most of the items, however some recipes do require the player to have reached a certain level. Carpentry level, however, affects crafted spear durability when crafted. Carpentry also affects repairing chances.
Constructing objects in the world, however, will affect the health of various objects, specifically walls, doors, etc. The health will scale to the player's skill level in the appropriate skill, adding 100 health per level.
Many recipes require tools that are not consumed in the recipe. The tools' durability doesn't go down when used, although some of the tool's fuel can be consumed.
